Re: AC/DC & POWERSTATION KIT BUILD THREAD

Thanks Joe. To put it to the theory test, I measure 37.7ohms over GND to +5v when the psu is removed. 5v / 37.7ohms is 0.133A, which requires massive heat dissipation. 17v rails measure about 660k, therefore about 1A. Could have used a 30VA transformer. My theory could be wrong. It's about time I le...

Re: AC/DC & POWERSTATION KIT BUILD THREAD

Hi Joe, For the last year I've been working on an 8 channel mic pre with AD/DA capability. It's basically an Amek Angela / M1000 mic pre front end, with a AD8000 back end. The voltages required are +/-17v, 5v and 48v. I'm using a Powerstation and a 2x18v 50VA supply. The concern is the 5v, and havin...
